InfoPath Dev

No, I have not set it to be web enabled because InfoPath is installed on the server. I lose functionality with the web version that I need for the form. Am I understanding correctly that even if the application is on the host server, it needs to be a web enabled form?

I've published a form to my SharePoint server, which has InfoPath installed. However, only people who are running InfoPath on their desktops seem to be able to open the form. Others receive an error message loading the form.
